How to add extra newline with 'puts' without sticking newline character into string?

Question

If I say

puts "Hello"

and decide to add an extra newline I need to do this:

puts "Hello\n"

Having this character in the string is ugly. Is there any way to do this without polluting my string?

Answer 1

Just make another call to puts:

puts "Hello"
puts

Answer 2

puts "Hello",""

Answer 3

I often find myself adding a constant in ruby to contain these characters

NEW_LINE = "\n"

puts "Hello" + NEW_LINE

I think it is more readable and makes a change to all newline characters easy if anyone ever decides to separate each line by something else at some later date.

Answer 4

Do you think this looks nicer?

puts "Hello"+$/

Answer 5

The reason Ruby uses "\n" for a newline is because its based on C. Ruby MRI is written in C and even JRuby is written in Java which is based on C++ which is based on C... you get the idea! So all these C-style languages use the "\n" for the new line.

You can always write your own method that acts like puts but adds new lines based upon a parameter to the method.

Answer 6

you can just write

p "Hello"
p 

That should work as well if you want to keep it short and simple

Answer 7

Well, I don't think an explicit newline is ugly. mipadi's answer is just fine as well. Just to throw another answer in, make an array of the lines then join the aray with a newline. :)

Answer 8

What you want fixed: input for script:

puts "Hello there"
puts "Goodbye"

Output from script:

Hello thereGoodbye

Fix for the problem: Input for script:

puts "Hello there"
puts
puts "Goodbye"

Output from script:

Hello there
Goodbye
